Description

[Technical field]

[0001] The present invention relates to a fixation device. More specifically, the present invention relates to a fixing device for simply and firmly fixing medical instruments and medical tubes, in particular medical instruments attached to the outside of a medical tube that is to be inserted into the human body. [Background technology]

[0002] 2. Description of the Related Art In the medical field, medical tubes such as catheters and cannulas are inserted into the body for the purposes of endotracheal suction, drug administration, nutritional management, drainage of bodily fluids, monitoring, and the like. Such medical tubes are maintained in an inserted state for a certain period of time in order to perform the intended medical procedure or treatment, and during that period, the medical tube and the medical instruments connected to the medical tube must be securely fixed and held to a support table or a specific position on the patient's skin to prevent them from falling out of the patient or interfering with the medical procedure of the healthcare provider.

[0003] Medical tubing and medical instruments connected to medical tubing are fixed in place using a large amount of adhesive tape, for example by first applying adhesive tape to a support base or a specific location on the patient's skin, placing the medical tubing or medical instrument on the adhesive tape, and then applying another layer of adhesive tape on top of that to fix the medical tubing or medical instrument in place.

[0004] However, conventional methods of fixing using adhesive tape or the like do not provide sufficient fixation of medical tubes or medical instruments, and there is a problem in that it is difficult to maintain a good fixation state, particularly when force is suddenly applied to the medical instruments. In addition, in order to maintain a good fixation state, there is a method of reinforcing the fixation using medical tape or bandage tape, but this method has the problem that the operation is complicated and it takes time before medical treatment can be performed.

[0005] There is ongoing research into fixation methods, devices, and fixtures that can solve these problems.

[0006] For example, Utility Model Registration No. 3204410 (Patent Document 1) proposes an adhesive sheet for fixing medical instruments that causes less skin irritation and can cover a wide area.

[0007] This adhesive sheet for fixing a medical instrument has one or more slits formed therein penetrating in the thickness direction.

[0008] Furthermore, JP 2015-154874 A (Patent Document 2) proposes an insertion member fixing device that can easily and reliably insert and fix an insertion member into the body, and reliably seal a hole formed in the body.

[0009] This insertion member fixing device fixes an insertion member to be inserted into the body, a base having a main body portion having an insertion hole through which the insertion member is inserted and inserted into a hole formed in a body, and a flange portion provided radially outward of the main body portion and adapted to come into contact with the body; a cap having a first pressing portion that is inserted into the insertion hole of the main body in the axial direction of the main body, and a second pressing portion that is provided radially outward of the first pressing portion and that is inserted into a through hole formed in the flange portion in the axial direction of the main body; a first annular elastic member that is disposed in the insertion hole of the main body portion, and is pressed in the axial direction of the main body portion by the first pressing portion that is inserted into the insertion hole when the cap is attached to the base, and is deformed so as to reduce an inner diameter thereof, thereby being in close contact with an outer surface of the insertion member; a second annular elastic member disposed radially outward of the main body portion, the second elastic member being pressed in the axial direction of the main body portion by the second pressing portion inserted into the through hole when the cap is attached to the base, and being deformed so as to expand its outer diameter, thereby coming into close contact with the inner surface of the hole; It is equipped with the following.

[0010] Furthermore, JP 2020-110223 A (Patent Document 3) proposes a fixing device for a tracheostomy tube that allows attachments such as an artificial nose or a catheter mount to be relatively easily fixed to the tip of the tracheostomy tube.

[0011] This tracheotomy tube fixture includes a holding plate made of an elastic material that can be positioned along the attachment from the side opposite to the side of the attachment that is connected to the tracheotomy tube, and a pair of belts that extend in the left-right direction from both ends of the holding plate, The holding plate is provided with a first through hole and a pair of second through holes arranged in the left-right direction with the first through hole therebetween, as a fitting portion capable of fitting with the attachment, At least a portion of the belt is provided with a hook-type hook-and-loop fastener that can be joined to the surface of the neckband of the tracheostomy tube.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the configuration of one embodiment of a fixing device according to the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments shown in the drawings, and various improvements can be made without departing from the spirit and scope of the present invention.

[0032] Fig. 1 is an explanatory diagram showing an example of a fixing device 1 according to the present invention, showing a state in which the fixing device 1 is attached to the head of a user. Fig. 2 is a perspective view showing an example of a device main body constituting the fixing device 1, and Fig. 3 is an explanatory diagram showing a state in which the device main body is deployed. In this specification, terms indicating directions such as up and down, front and back, left and right, etc. are based on the user who wears the fixation device 1. Therefore, when the user is wearing the fixation device 1, the surface visible from the surroundings is the front surface (front side), and the surface facing the user's body is the back surface (rear side).

[0033] The fixing device 1 of this invention, as shown in FIG. 1, is to be worn on the user's head H when in use, and is composed of a device main body 2 configured to be able to be worn on the user's head H, and a holding means 3 that can be attached to the device main body 2 and is configured to be able to hold or wrap medical instruments or medical tubes.

[0034] As shown in FIGS. 2 and 3, the device main body 2 is configured to include a back head contact portion 21, an upper mounting portion 22, and left and right mounting portions 23, 24.

[0035] The rear head contact portion 21 is a portion that contacts the rear of the user's head when the fixing device 1 is worn, and has a contact surface (rear head contact surface) 21a on its back surface that contacts the rear of the user's head.

[0036] 2 and 3, the rear head contact portion 21 is formed of a plate-like body of the required size and is configured to have a rectangular shape having a vertical (up-down) length that is the same as the vertical length of the left and right mounting portions 23, 24, and a horizontal (left-right) length that is the same as the left-right length of the upper mounting portion 22. There is no particular limitation on the size of the rear head contact portion, and it can be set appropriately depending on the user's body type, purpose, etc. The shape of the back of the head contact portion is not particularly limited and can be appropriately selected depending on the application, etc. Examples of the shape include a circle, an ellipse, a triangle, and a rectangle (square, oblong).

[0037] In this embodiment, the rear head contact portion 21 is made of a material that is breathable and cushioned and fits the rear head of the user. As the material, for example, a cushion material in which polyester elastomer or urethane is woven can be selected. Specifically, in this embodiment, the rear head contact portion 21 is formed integrally with the upper mounting portion 22, and is made of an outer material made of nylon and a lining material made of urethane with foamed urethane sandwiched between them, thereby giving it elasticity, but is not limited to this configuration. The material constituting the outer fabric and / or the inner fabric may have a mesh structure. Furthermore, in this embodiment, the rear head contact portion 21 is formed integrally with the upper mounting portion 22, but it is also possible to form the rear head contact portion 21 and the upper mounting portion 22 as separate bodies rather than forming them integrally.

[0038] The upper attachment portion 22 is a band-like member extending upward from the upper edge of the occipital contact portion 21, particularly from the upper edge of the central portion in the left-right direction, and is configured to extend over the top of the user's head and to the forehead when the fixing device 1 is attached. In addition, in Figures 2 and 3, at least the tip side of the surface of the upper attachment part 22 is made of a material with hook-and-loop function, such as pile fabric, so that it can be engaged with a hook-and-loop fastener (hook-shaped hook-and-loop fastener) provided on another attachment part.

[0039] The left and right attachment portions 23, 24 are belt-shaped extending laterally from at least one of the left and right end edges of the occipital contact portion 21, and are configured to be wrapped around the left or right head and forehead of the user, so as to conform to the left or right head and forehead (particularly the forehead) of the user when the fixing device 1 is attached.

[0040] 2 and 3, the upper mounting portion 22 and the left and right mounting portions 23, 24 are all made of a stretchable material having elasticity, and are configured to be stretchable at least in the longitudinal direction. Therefore, the fixing device 1 is configured to fit the user's head when it is worn. Specifically, in this embodiment, the upper mounting portion 22 and the left and right mounting portions 23, 24 are all constructed with a foamed urethane sandwiched between an outer material made of nylon and an inner material made of urethane, but the present invention is not limited to this configuration. The material constituting the outer fabric and / or the inner fabric may have a mesh structure.

[0041] In this embodiment, the left and right mounting portions 23, 24 extend to the left and right with approximately equal lengths, but the lengths of the left and right mounting portions 23, 24 may be different. Further, a configuration may be adopted in which either one of the left and right mounting parts 23, 24 is provided and wrapped around the user's head H, and then joined to the back head contact part 21 (for example, its outer surface side).

[0042] The width (left-right length) of the upper mounting part and the width (top-bottom length) of the left and right mounting parts can be set appropriately depending on the user's body type, etc., and there are no particular restrictions. For example, the left-right length of the upper mounting part can be set to approximately 1 to 10 cm, and the top-bottom length of the left and right mounting parts can be set to approximately 1 to 10 cm.

[0043] There is no particular limitation on the ratio between the left-right length of the upper mounting portion and the up-down length of the left and right mounting portions, but it can be set to, for example, 2:1 to 2:3.

[0044] In addition, in Figures 2 and 3, the device main body 2 constituting the fixing device 1 has a structure in which the rear head contact portion 21, the upper mounting portion 22, and the left and right mounting portions 23, 24 are integrated by forming a single plate-like body into an approximately inverted T shape, but it is also possible to form the rear head contact portion 21, the upper mounting portion 22, and the left and right mounting portions 23, 24 as separate bodies rather than forming them integrally.

[0045] The device main body 2 of such a configuration is constructed (formed) in a state where it is attached to the user's head H by joining the upper attachment part 22 and the left attachment part 23 and / or right attachment part 24 to each other at the front side (forehead) of the user's head H, particularly near the forehead.

[0046] In this embodiment, the upper mounting portion 22 is placed on top of the left mounting portion 23, and then the right mounting portion 24 is placed on top of the upper mounting portion 22 and joined together, but there is no particular restriction on the order in which each mounting portion is joined.

[0047] In this embodiment, the attachment parts are joined at the front of the user's head H by constructing the surface of each attachment part from a material with hook-and-loop function such as pile fabric, and providing hook-and-loop fasteners (hook-shaped hook-and-loop fasteners) 22b, 24a on the surface that abuts the surface of the attachment part, which are configured to be able to engage with the material with hook-and-loop function; however, there are no particular limitations on the method of joining each attachment part. For example, as the joining means, a method of using other known means such as buttons, hooks, adhesive tape, magnets, etc. can be selected.

[0048] Of the upper mounting portion 22 and the left and right mounting portions 23, 24, the surfaces (back surfaces) that come into contact with the user's head H (particularly the forehead) can be provided with a means for generating friction by adhering to the user's forehead, such as uneven processing, as shown in Figures 2 and 3, i.e., a non-slip surface 25 can be formed.

[0049] In this invention, as shown in FIG. 1, a holding means 3 for holding or enclosing a medical instrument or medical tube to be fixed is attached to the device body 2.

[0050] The holding means 3 is attached to a fixing area 22a of a required size formed at a predetermined position on the surface of the device body 2. The fixing region 22a can be formed at a position on the surface of the device main body 2 where a medical instrument or a medical tube is fixed, for example, on the front surface (surface) of the upper mounting part 22. Preferably, the fixing region 22a is formed on the front surface (surface) of the upper mounting part 22 at an arbitrary position between the top of the head and the forehead of the user when the fixing device 1 is worn.

[0051] 2 and 3, the fixing region 22a is formed on the front surface (surface) of the upper mounting part 22 in a region located near the forehead of the user when the fixing device 1 is attached. Therefore, when the holding means 3 is attached to the fixing region 22a, the holding means 3 is located near the user's forehead on the front (surface) of the upper mounting portion 22 when the fixing device 1 is attached, as shown in FIG. Therefore, medical procedures, particularly those performed on or through the oral cavity, can be performed more easily. The medical procedures include, for example, surgery, treatment, and examination.

[0052] There are no particular limitations on the means for attaching and fixing the holding means 3 for holding a medical instrument or a medical tube to the fixing region 22a. In FIG. 1, the holding means 3 is configured such that at least the contact surface of the fixing region 22a with the holding means 3 is made of a material with hook-and-loop function such as pile fabric, while a hook-and-loop fastener (hook-shaped hook-and-loop fastener) 31c configured to be capable of engaging with the material with hook-and-loop function is provided on the contact surface of the holding means 3 with the fixing region 22a, thereby making it possible to attach and detach it to the fixing region 22a. The method of attaching and fixing the holding means 3 to the fixing area 22a is not limited to the above configuration, and other known attaching and fixing means such as buttons, hooks, adhesive tape, magnets, etc. can be used.

[0053] The holding means 3 is configured to hold or encase a desired medical instrument and / or medical tube, as shown in FIG. Therefore, there are no particular limitations on the shape of the holding means 3 as long as it is capable of holding or encasing the medical instrument and / or medical tube. The holding or enveloping means may be selected from known or future developed means, such as strings, tapes, fasteners (particularly plastic fasteners), and the like.

[0054] There are no particular limitations on the medical instruments and medical tubes, so long as they can be fixed to the user's head. Examples of the medical device include a medical device attached to the outside of a medical tube that is inserted into the human body, such as an artificial nose. Examples of the medical tube include a catheter, a cannula, and a nasal intubation tube.

[0055] There are no particular limitations on the size and shape of the holding means, and they can be set appropriately depending on the medical instrument or medical tube to be fixed. The size and shape of the holding means may be, for example, rectangular with a vertical length of about 5 to 10 cm and a horizontal length of about 5 to 30 cm.

[0056] In FIG. 6, the holding means 3 is composed of a holding means main body 31 made of a single plate-like body having a required shape, and the holding means main body 31 is composed of elastic cloth or fabric. With this configuration, the holding means 3 is capable of holding a desired medical instrument or medical tube.

[0057] In FIG. 6, the holding means 3 is configured of a plate-like body having a substantially H-shape in a plan view. Specifically, the holding means 3 is configured such that when the artificial nose as the medical device 4 is held, an opening is formed for allowing the flange portion 4a of the artificial nose to protrude from the holding means 3 by cutting out the central portions of both left and right end edges by a required length toward the inside in the left-right direction (forming notches 31a, 31b), thereby forming a pair of holding pieces 31d, 31f protruding to the left and a pair of holding pieces 31e, 31g protruding to the right. Therefore, the holding means 3 is capable of securely and firmly holding the artificial nose by wrapping the holding pieces 31d, 31e formed at its front end around the outer periphery of the front tube portion 4b of the artificial nose, and the holding pieces 31f, 31g formed at its rear end around the outer periphery of the rear tube portion 4c. Therefore, the holding means having such a configuration can firmly hold and fix a medical instrument, such as an artificial nose, which is attached to the outside of a medical tube that is inserted into the human body.

[0058] In Figures 5 and 6, the holding pieces 31d, 31e (or 31f, 31g) are joined together by making the surface of the holding piece 31e (or 31g) out of a material with hook-and-loop function such as pile fabric, and by providing an engagement piece 32a (or 32b) protruding from the tip edge of the other holding piece 31d (or 31f), and by providing a hook-and-loop fastener 32c configured to be able to engage with the material with hook-and-loop function on at least the contact surface of the back surface of the engagement piece 32a (or 31g) with the holding piece 31d (or 31f). However, there are no particular limitations on the method of joining (engaging) the holding pieces together, and other known joining methods can be used.

[0059] 5 and 6, the holding means 3 wraps (spins) around the outer periphery of the medical device 4 in the left-right direction to encase the medical device 4, but there is no particular limitation on the winding direction.

[0060] When the holding means 3 holds or encases a medical instrument or a medical tube, as shown in FIG. 7, an interposition member 5 can be interposed between the holding means 3 and the medical instrument or medical tube. With this configuration, the medical instrument or medical tube is securely held or wrapped in the holding means 3 . In FIG. 7, the intermediate member 5 is made of an elastic material such as urethane foam.

[0061] 1 to 3, the fixing device 1 includes a cushion portion 6 extending downward from the lower end edge of the back head contact portion 21. As shown in FIG. The cushion portion 6 is configured to extend downward from the lower edge of the occipital contact portion 21 along the user's neck when the fixing device 1 is worn, and serves as a cushion for the area below the occipital region. Therefore, the user can receive medical treatment from a medical professional more comfortably while wearing the fixing device 1.

[0062] In this embodiment, the cushion portion 6 is formed to have a substantially trapezoidal shape in a plan view, but there is no particular limitation to the shape. In this embodiment, the cushion portion 6 is made of a material that has cushioning properties and fits the back of the user's head, but there are no particular limitations on the material of the cushion portion 6. As the material, for example, a cushion material in which polyester elastomer or urethane is woven can be selected. Specifically, in this embodiment, the cushion portion 6 is constructed by sandwiching foamed urethane between an outer layer made of nylon and an inner layer made of urethane, but is not limited to this configuration. The material constituting the outer fabric and / or the inner fabric may have a mesh structure.

[0063] In FIG. 8, the holding means 3 in a state in which the medical instrument and / or medical tube is held or wrapped is more firmly fixed to the user's head H by the restraining means 7.

[0064] As shown in Figure 8, the restraining means 7 presses the medical instrument and / or medical tube or the upper surface of the holding means 3 holding or encasing the same toward the user's head H, thereby restraining the medical instrument and / or medical tube or the holding means 3 to the user's head H and making it possible to prevent the medical instrument and / or medical tube from moving. Therefore, there are no particular restrictions on the shape of the restraint means, so long as one end can be engaged with the medical instrument and / or medical tube or the holding means 3 when in contact with the medical instrument and / or medical tube or the upper surface of the holding means 3 holding or encasing the same, and the other end (the end opposite to the one end) can be engaged with the back of the user's head. The restraining means may be, for example, a belt-like, string-like or band-like means, both ends of which may be connected together as necessary. In this case, the restraining means may be provided with a connector that enables both ends of the restraining means to be connected to each other.

[0065] In Figure 8, the restraint means 7 is configured by connecting both ends of a belt-like member to each other via a connector 7a that allows the length to be changed to form a ring, and is configured so that when one end of the member abuts against the upper surface of the tube portion 4b on the user's side of the medical device (artificial nose) 4, the part facing this one end (abutment portion) is engaged with the back of the user's head, preferably the occipital protuberance. Therefore, if the restraint means 7 is configured to be length adjustable using an appropriate means and is adjusted to an appropriate length so that the medical device is in a taut state when worn by the user, the upper surface of the medical device will be pressed toward the user's head.

[0066] Next, an example of a method for mounting the fixing device 1 of the present invention will be described. In FIG. 3, the device main body 2 constituting the fixing device 1 is in a state in which the head contact part 21, the upper mounting part 22, and the left and right mounting parts 23, 24 are not joined together. With the contact surface 21a of the head contact part 21 of the device main body 2 in contact with the back of the user's head, the left attachment part 23 is wrapped around the left side of the head and the front of the head of the user, and then the upper attachment part 22 is extended over the top of the user's head to the forehead and overlapped and joined onto the left attachment part 23. Furthermore, the right mounting part 24 is wrapped around the right side of the head and the forehead of the user, and is overlapped and joined onto the upper mounting part 22, so that the device main body 2 is mounted on the head H of the user.

[0067] On the other hand, the holding means 3 holds or encases the medical instrument or medical tube to be fixed.

[0068] Thereafter, the holding means 3 is attached to the fixing area 22a provided on the device main body 2 using a specified attachment method, thereby fixing the medical instrument or medical tube to the user's body, particularly the head.

[0069] Thus, medical instruments and medical tubes, particularly artificial noses, can be fixed simply and firmly.

[0070] As shown in Figure 4, the fixing device 1 of such a configuration can be composed of a device main body 2 having a rear head contact portion 21, an upper mounting portion 22, and left and right mounting portions 23, 24, and a holding means 3 attached to a fixing area formed in the device main body 2 (particularly the upper mounting portion 22), and is used by being attached to the user's body, particularly the head. In particular, in the fixing device 1, the medical tube or the medical instrument including the same, which is held or wrapped by the holding means 3, is fixed to the head of the user. Therefore, the fixing device 1 can be used as a fixing device for fixing a medical tube such as a medical tube (nasal intubation tube) inserted into the nasal cavity through the nostril, or a medical instrument equipped with the same, used when performing medical procedures, particularly medical procedures performed on or through the oral cavity.

[0071] Conventionally, medical tubes and medical instruments connected to medical tubes have been fixed using a large amount of adhesive tape, medical tape, bandage tape, etc., which has led to problems such as insufficient fixation of the medical tubes and medical instruments, and the problem that it is very cumbersome and takes a long time before medical procedures can be performed. Furthermore, there has been a problem that the adhesive used in the adhesive tape may cause peeling irritation to the skin, resulting in skin disorders for the user. In this invention, the fixing device 1 can fix the medical tube or the medical instrument connected to the medical tube to the user (human body) by simply attaching the holding means 3, which already holds or contains the medical tube or the medical instrument connected to the medical tube, to the fixing area formed at a predetermined position while the fixing device 1 is worn on the user's head. Therefore, the medical tube and the medical instruments connected to the medical tube can be fixed very easily and safely since no skin damage is caused to the user.

[0072] Furthermore, according to the present invention, it is also possible to provide a method for fastening a medical instrument or a medical tube, in which the fastening device is used to simply and firmly fasten a medical instrument that is attached to the outside of a medical tube that is to be inserted into the human body, and such a fastening method is also encompassed by the present invention. [Industrial Applicability]

[0073] This invention relates to a fixing device for holding and fixing medical instruments and medical tubes, particularly artificial noses, which enables medical instruments and medical tubes to be easily and firmly fixed to the human body, particularly the user's head. Therefore, the present invention can be widely used as a fixing device for simply and firmly fixing medical instruments and medical tubes, especially artificial noses and the like.
